A Complete Solution-Oriented Guide to Calming the Nervous System, Reducing Hyperarousal, and Restoring Emotional Regulation in Trauma Recovery
One of the most distressing features of Post-Traumatic Stress Disorder (PTSD) is emotional reactivity. Small triggers can provoke intense fear, anger, panic, or shutdown responses that feel uncontrollable and overwhelming.
This is not a character flaw or lack of coping skills. Emotional reactivity in PTSD is driven by a nervous system that remains stuck in survival mode, constantly scanning for danger.
Gamma-Aminobutyric Acid (GABA) is the brain’s primary calming neurotransmitter. Supporting GABA activity offers a direct, biological pathway to reducing emotional reactivity, calming hyperarousal, and restoring a sense of internal safety.
Emotional reactivity refers to intense, rapid emotional responses that are disproportionate to the present situation.
In PTSD, this often appears as:
These reactions originate in the brain’s threat-detection systems, not conscious choice.
PTSD involves chronic activation of the sympathetic nervous system.
This leads to:
For healing to occur, the nervous system must regain access to inhibitory, calming signals.
GABA (Gamma-Aminobutyric Acid) is the brain’s main inhibitory neurotransmitter.
Its primary function is to reduce excessive neuronal firing, acting as a natural brake on the nervous system.
When GABA signaling is strong, the brain can distinguish between real danger and safety.
GABA helps regulate emotional responses by:
Without adequate GABA, emotional reactions escalate rapidly and linger longer.
Chronic trauma exposure disrupts inhibitory neurotransmitter systems.
Contributors to low GABA activity include:
This imbalance leaves the nervous system without sufficient braking capacity.
Hyperarousal is a core PTSD symptom cluster.
Low GABA activity contributes to:
Enhancing GABA signaling helps shift the body toward parasympathetic calm.
The amygdala relies heavily on GABA input to regulate fear responses.
When GABA is insufficient, the amygdala reacts as if danger is present even when it is not.
Supporting GABA helps reduce exaggerated startle responses and fear-based emotional spikes.
Typical dosages range from 100–500 mg per use.
Week 1: Introduce low-dose GABA support, prioritize sleep.
Week 2: Add yoga and pranayama practices.
Week 3–4: Maintain routine, focus on trigger awareness and calm recovery.
Some people feel calming effects within minutes, especially with sublingual forms.
No, GABA is non-addictive.
No. It supports regulation but does not replace trauma therapy.
Yes, when used appropriately and under guidance.
Emotional reactivity in PTSD is driven by a nervous system that has lost its inhibitory balance.
GABA restores the calming signal that allows the brain and body to feel safe again.
When combined with trauma-informed therapy, nutrition, movement, and breathwork, GABA can play a powerful role in reducing reactivity, improving emotional control, and supporting long-term recovery.
